Bruce Hatchett of Pacific Solar & Wind gave me a call a few weeks ago to tell me they were installing a Bergey 15 kW wind turbine in Tehachapi, wondering if I wanted to get some photos of it. “I don’t do that anymore,” I whined to Hatchett. “I have a full agenda playing with electric cars.”

Small Scale Renewables Sven Ruin

Small-Scale Renewable Energy Systems is a slim 210-page book on hybrid renewable projects by Swedish authors Sven Ruin and Göran Sidén.

Makani Prototype Jpg

This week, a 13-year experiment in harnessing wind power using kites and modified gliders finally closes down for good.

Cheaper turbine models, possible demand from the growing microgrid market, and an intensifying focus on distributed energy resources in general may all contribute to putting some wind back in the sails of distributed wind companies — despite the obvious challenges ahead.

In the research for his new book, Vaughn Nelson has been dredging up some amazing videos. (See Hywind Scotland Floating Offshore Wind Turbine Video.)

Davis was CEO of Dragonfly Industries International, LLC, which sought to build a wind farm on 300 acres near in Elm Springs for electric power generation in 2015.

It is uncertain if the Company’s efforts (i) to address its cash constraints and its legal difficulties with Comerica and/or (ii) to effect one or more strategic transactions will be successful.

I’ve been alerted to an error in the second edition of Wind Power (2004): Renewable Energy for Home Farm and Business.

I’ve added several rare photos and scans Vaughn Nelson found in his files from the 1970s. Nelson, one of the wind industry’s pioneers, has an extensive collection of experimental wind turbines from the period.

Kidwind's Michael Arquin Judges A Wind Tunnel Test Of One Bladed Wind Turbine Toy Model At The 2017 Small Wind Conference Competition An Annual Feature Of The Conference. It Didn't Win.

Since 2010 the small wind industry in North America has been in steep decline. First Congress turned its back on the industry in the United States. Then the descent accelerated with the rapid fall in the cost of solar energy. Why install a small wind turbine when solar had become so cheap.
